Myinvention relates yto air @Xllusting apparatus, 'andv more particularly to suction tubes which are used in connection with v`nature of which will become apparent as such apparatus.

When .an apparatus of the class described is used as a vacuum or suction cleaner, it is often desirable that the fan or other suction device be provided with a detachable flexible` suction hosein order that the operator `10 may be enabled to Vuse the apparatus for cleaning remote corners or crevices which could not be easily reached by the main sucltion nozzle of the cleaner. f

Although such adetachable ieXible tube 15 fills'. a number of needs, there are some uses to which it is not readily applicable for-the reason vthatv -it is not always convenient to completelydetach the tube! from ythe fan when its use is temporarily discontinued. ,y 20 Anotherdisadvantage is that, since `the tubes heretofore usedy have been of 'fixed length and have been rigidly connected atione end to the suction fan casing, the moving of the'v nozzle end of the 4tube (over areasnear 4the therefrom, resulted 'in some kinking Aand 4twisting of the tube..

The main object of my invention is tofoyerl s forv closing the housing come these disadvantagesbythe provision of a-housing xed to a suction' fan casing, in which housing a flexible suction vtube .,Sbtele scopically mounted and adapted-t0 be yeX-f: v View taken on .the line 7 7 .of Figure 6.

.jhausting apparatus generally designatednB.

The apparatus includes an Aexhauster C havinga lcasing 4t andra multi-*blade fan 4a .of al well-known `.construction mounted thereinand driven .by a motor 4b, alsomount..

. ed V,in theta-n .casing-the'. motor receiving its Y. power y from v a battery One :ofi the motor terminalspis grounded to the body of ,the vehicle, and ytheother isconnected to 50. vfors.exhausting the air romAt-hevinterior of thegnongrounded `terminal.ofthe battery 5 by means of wires 6--6; and a switch 7 is interposed between said wires for controlling the motor circuit.

The casing is provided with an inlet opening 8 and an exhaust opening 9, the latter being arranged to exhaust air exteriorally of the vehicle body. The inlet opening 8 is formed in a forwardly extending pipe 8a, which pipe is threaded at its outer end to receive an internally threaded coupling 10, the inner wall of the other end of the coupling being smooth and of a size to closely embrace the inner or rear end of a rigid tubular housing D,.the outer end of the .housing being supported by the seat riser in a manner to be hereinafter more particularly described.

' The outer end ofthe housing is provided with an enlarged portion 11, the inner wall L 'of the necked-in inner end of which is preferably detachably connected to the tubular housing and serves as a support for the latter. The enlarged portion 11 extends through an aperture 12 in the riser 2 and is provided at its outer end with a flange 13 which is preferably positioned in a seat 13a in the front face of the seat riser. It will thus be seen that the housing D and theenlarged portion 1l which forms a part thereof are rigidly supported at the inner end on the fan casing and at the outer end by the seat riser which for this purpose is, in effect, a support. It is also apparent that the housing communicates at itsA inner end with the y intake opening 8 of the fan casing and is in open communication at its outer end with the interior of the vehicle.

A flexible tube generally designated E comprising a flexible fabric section 15, a tubular metallic coupling 16 connected to the inner end thereof, and a suction nozzle 17 attached to the outer end thereof is telescopically mounted in the housing D and is adapted to be extended from the open end of the housing for the purpose specied.

In order to obtainvthe most eflicient'rei sultswith my apparatus, the flexible tube,

when in any position of adjustment, should have substantially fluid tight connection to the housing. To this end'Iprovide, at the inner end of the tube, a compressible washer 18 extending around the metal coupling 16 and arranged to have sliding contact with the inner wall of the housing. In order that this Washer be maintained against longitudinal displacement with respect to the.

tube, the latter is formed at its extreme inner end with a peripheral flange 19, and interposed between this flange and the comp ressible washer is a rubber'or other elastic. V,washer-retaining ring 20 extending around the tube.

A second and similar retaining ring 21 is positioned on the opposite side of the washer and in abutting relation thereto. It will be seen that the two-retaining rings the innerk face of the flange.

Y accidentally completely withdrawn from the housing. For accomplishing this purpose, I provide the outer end o'f the housing with an abutment which preferably is in the form of an inwardly extending flange 22 which,

.if desired, may be provided with a rubber cushioning ring 23 positioned within the housing and cemented thereto so as to be seated against the inner wall thereof and It will be observed that the peripheral flange 19 and the inwardly extending flange 22 are disposed in overlapping relation, so that, if the flexible tube is withdrawn from the housing, the washer retaining ring 21 will engage the cushioning washer 23 and further movement of the flexible tube will be pre-` vented.A

In order that the nozzle 17 be not unduly in evidence when in its stowed away position, there is preferably provided a reticulated door 24 having openings 25, the door being hinged to the flange 13 on the housing as at 26. A springcatch 27 serves to retain the door in closed position. Y

IWhen the flexible tube is not in use for cleaning various parts of the interior of the vehicle, the tube may be slid completely into thel housing so that the suction nozzle 17 will beY encased in the enlarged portion 1l of the housing. If it is desired that, with the tube in this position, the apparatus be used as a means for improving the ventilation ofthe car, the motor and fan may be driven just las though the apparatus were Vbeing usedfor cleaning purposes. The air will be drawn inthrough the openings in the doorand the suction nozzle and then Y-exhausted through the exhaust opening 9.

v When the apparatus is used as a ventilator, in most casesthe air which enters the interior of the car through the cracks around the doors and Windows will ordi* narily be suflicient to replace the air exhausted through the suction tube, but, if desirable, more air may be introduced through a ventilator such as that indicated at 28 such or similar ventilators being standard equipment on most vehicles.

The operation of thevapparatus, either as a cleaner or as a ventilator, is obvious from the preceding description and will not beY described in detail. It is sufficient to say `that the tube may be completely stored in the housing and that the apparatus may remain inoperative, or the fan may be driven when the tube is stored in the housing and the apparatus then functions as aventilator, or, if' desired, thedoor may be opened, the

'tube withdrawn through the aperture in theV riser, the fan started, and the suction nozzle then be used to clean various partsofthe interior of the car. l Y

It is to be understood that, whenever the conditions under `which the air exhauster is used are such that an unusually long flexible tube is necessary in order that surfaces somewhatv remote from the fixed housing maybe reached by the suction nozzle, the K flexible tube may be formed of a number of telescopically arranged sections. The particular arrangement of these sections would be similar to the connection between the single flexible tube E and the fixed housing D shown in the drawings.'

I claim:

The combination with a support provided with an aperture; of an air exhausting apparatus `including a casing having` exhaust and intake openings; a tubular housing connected at its inner end to said casing to communicate with the intake openingyand provided at its outer end with an enlarged portion extending into said aperture and secured to said support; Ya flexible tube telescopieally mounted within said housing in substantially fluid tight relation thereto and adapted to be extended through said aperture; and a suction nozzle on the outer end of the tube adapted to be positioned within the'enlarged portion of said housing when K the parts are in telescopic relation.

In testimony whereof, I have hereuntov JOHN H. mons,l

subscribed my name.
